This adds functions to enable/disable clocks and reset to on-chip peripherals.

Subject: [PATCH 1/4] Add microsecond boot time measurement

This defines the basics of a new boot time measurement feature. This allows
logging of very accurate time measurements as the boot proceeds, by using
an available microsecond counter.
